Don't get the 15peice pricepoint one it only has folding allen keys.

NIce tools aquired over a period of time as they are needed will be nicer. Just think that for pretty much everything other a headset buying the nice tools will be cheaper then paying the shop for the labour. On the other hand it is nice to not have to worry about buying a tool when ever you have to do some work so maybe one of the sets would be nice.

I'd probably go with the 21 peice pricepoint cause it is cheaper and you will end up having to augment all of them at some point. I'm not sure if the spanner in it will work for your lockring though. Also I don't like how the zoom for the performance onces prevents me from really seeing whats inside.
